Research On Parts Resource Classification,Modeling And Sharing Technologies And Their Application In Parts Library

Manufacturing enterprises customer-oriented implementing product rapid development and design have to be confronted with challenge of product diversification especially the component as well related information resourse. Enterprises must optimize component resourse by information technology and standardization technology. The key to get this goal is to implement parts library resource managenment efficiently.The parts library resource managenment is kind of component resourse management methodology to the product diversification challenge supported by IT, standard technology as well design methodology, which could promote enterprise to implement rapid product development and design process even efficiently through parts library resource sharing and reuse. The theory, architecture and key technologies of parts library resource managenment were discussed. With financial support by application project, the software prototype was developed.In the first chapter, the modern market environment of manufacturing enterprises come into being was analyzed. The product diversification challenge that enterprise has to be confronted with was proposed, for which product information management methodology product family oriented was summarized. The development history and the state of the parts library resource managenment were reviewed. Then, the research motive and content of this dissertation were proposed.In the second chapter, the requirement of parts library resource management under product diversification challenge was proposed. After comparing and analyzing current parts library, the concept of parts library resource managenment was proposed, the essence, implement method and estimate mechanism in which were brought forward. At last its key technologies for parts library resource managenment implementing were analyzed.In the third chapter, to the problem of current parts resourc classification methods were always created from only one viewpoint, a parts resource general classfication model (PRGCM), which was based on the ontology, was presented. This modeling methodology included the conceptual analysis and the logical hierarchy model specification. Moreover, the implementing process of the PRGCM, which included the preparing phase, modeling phase and implementing phase, was put forward to acquire parts resource classifcation pattern finally for enterprise building parts library. In the fourth chapter, the requirements of parts family modeling were analyzed in detail. Then, a muti-view parts family resource model (PFRM) was presented. Its content and logical structure was discussed. It was classified into three segments: general model, represent modl and view model. In order to implement these models in a whole, based on standardization and normalization technologies, the concept, theory and implement methods of master document and article characteristic table technologie were studied. On the basis of PFRM, the parts library was built, some main issue such as its codeing system, storage mechanism and information integration mothod were discussed.In the fifth chapter, to the toughest problem of data heterogeneity and distributing when integrating various data sources via internet, service-oriented distributed part resource library architecture are established to integrate and sharing multiple enterprise part libraries resource. A fully automatic integration process based on virtual integration orient to each distributed parts library contains a self-parts classification model was proposed by references the shared PRGCM. After that, to the structured data characteristics of parts library, an unified distributed parts library resources acquisition access was built. In order to acquire the best-suited requirement component, a heuristic parts family searching algorithm and parts match method based on article property similarity degree were designed orderly. At last, the implementing process of all above method was supported by web service technology.In the sixth chapter, on the basis of above fundamental, the parts library resource management prototype system including its architecture and function model, was constructed. Then the parts library resource management system was applied in an auto parts manufacturing enterprise. The main functions as well screen-shots of this system applied to product rapid design were displayed. All the methods, technologies and system of the research in the dissertation were validated.The last chapter was conclusion and outlook. The achievements of the dissertation were summarized, and the innovations were pointed. The future research works were put forward to outlook.
